Definitions

  • the present invention relates to a lubricant composition for a limited slip differential (LSD) of a car. More specifically, it relates to a lubricant composition for LSD which is excellent in oxidation stability and the prevention ability of the chattering (abnormal noise) of an LSD device incorporated in the differential of a car and which can be suitably applied to LSD of a studless tires-carrying car whose demand increases mainly in cold districts.
  • LSD limited slip differential
  • a wet multiplate clutch is used, and its differential controlling force is maintained by the frictional force of a metallic plate.
  • a lubricant for this LSD is required to have extreme-pressure properties of a GL-5 class, and thus the lubricants containing a sulfurphosphorus additive and a friction modifier have been heretofore used.
  • a lubricant composition having the desired characteristics can be obtained by adding a phosphate amine salt and a borated ashless dispersant to a base oil, and then adjusting a ratio between a nitrogen content and a phosphorus content and a ratio between a nitrogen content and a boron content.
  • the present invention has been completed on the basis of such a knowledge.
  • the present invention is directed to a lubricant composition for LSD of a car which is obtained by adding a phosphate amine salt and a borated ashless dispersant to a base oil comprising a mineral oil and/or a synthetic oil, a ratio (N/P) of a nitrogen content (N) to a phosphorus content (P) in the composition being 0.5 or more, and a ratio (N/B) of the nitrogen content (N) to a boron content (B) in the composition being 4 to 10.
  • a lubricant composition for LSD of a car which is obtained by adding a phosphate amine salt and a borated ashless dispersant to a base oil comprising a mineral oil and/or a synthetic oil, a ratio (N/P) of a nitrogen content (N) to a phosphorus content (P) in the composition being 0.5 or more, and a ratio (N/B) of the nitrogen content (N) to a boron content (B) in the composition
  • the base oil for the lubricant composition of the present invention there can be used conventional lubricating oils for LSD, various kinds of mineral oils and synthetic oils, and mixed oils thereof. No particular restriction is put on the kind and properties of base oil, but preferable are the mineral oils and/or the synthetic oils in which a kinematic viscosity at 100°C is in the range of 1 to 50 cSt.
  • the suitable mineral oil and/or synthetic oil can be suitably selected in compliance with a use and the like from the various kinds of them.
  • the mineral oils include paraffinic mineral oils and naphthenic mineral oils
  • suitable examples of the synthetic oils include polymers and copolymers of olefins, esters of dibasic acids, polyglycols and hindered esters.
  • the lubricant composition of the present invention can be obtained by blending the above-mentioned base oil with a phosphate amine salt and a borated ashless dispersant.
  • the phosphate amine salt various kinds of compounds are present, but preferable examples of the phosphate amine salt include amine salts of phosphates and amine salts of phosphites.
  • Typical examples of the phosphate amine salt include amine salts of alkyl acid phosphates having an alkyl group of 10 to 20 carbon atoms (e.g., amine salts of oleyl acid phosphates and amine salts of lauryl acid phosphates), and amine salts of alkyl hydrogenphosphites.
  • the borated ashless dispersant various kinds of compounds can be used, but preferable examples of the borated ashless dispersant include reaction products (e.g., a reaction product of polybutenylsuccinimide and boric acid) of alkenylsuccinimides or alkenylsuccinamides having an alkenyl group of, preferably, 20 to 250 carbon atoms, more preferably 35 to 180 carbon atoms and boron compounds (e.g., boric acid and borates).
  • reaction products e.g., a reaction product of polybutenylsuccinimide and boric acid
  • boron compounds e.g., boric acid and borates
  • the amounts of the phosphate amine salt and the borated ashless dispersant are determined so that a ratio (N/P) of a nitrogen content (N) to a phosphorus content (P) in the composition may be 0.5 or more, preferably 0.7 to 1.0 and so that a ratio (N/B) of a nitrogen content (N) to a boron content (B) in the composition may be 4 to 10, preferably 6 to 9.
  • the weight ratio of N/P is less than 0.5, the lubricant composition are poor in frictional properites, and chattering is liable to occur and the abrasion of a friction plate increases. Furthermore, if the weight ratio of N/B is more than 10, heat resistance deteriorates and sludge is liable to be generated. Conversely, the weight ratio of N/B is less than 4, the frictional properites deteriorate.
  • the amounts of the respective components in the lubricant composition of the present invention are determined so as to be in the above-mentioned ranges, but in addition to meeting the above-mentioned ranges, it is more preferable that the amount of the phosphate amine salt is in the range of 1 to 10% by weight, preferably 3 to 8% by weight based on the weight of the composition, and the amount of the borated ashless dispersant is in the range of 0.1 to 2% by weight, preferably 0.5 to 1.5% by weight based on the weight of the composition.
  • the desired performance can be further effectively exerted by meeting these requirements and determining the amounts of the elements in the lubricant composition in the following ranges.
  • a sulfur content to 1.5-5.0% by weight, a phosphorus content to 0.15-0.40% by weight, a nitrogen content to 0.08-0.30% by weight and a boron content to 0.01-0.04% by weight, respectively.
  • the lubricant composition of the present invention comprises the above-mentioned essential components, but if necessary, various kinds of additives can be added to the lubricant composition.
  • the additives include an extreme pressure agent (an olefin sulfide, sulfurized fats and oils or the like), an abrasion-resistant agent (a phosphate, a phosphite or the like), an antioxidant (phenol or the like), a defoaming agent (an organic silicone compound or the like), an ashless dispersant (succinimide or the like), a viscosity index improver (polymethacrylate or the like), a pour point depressant (polymethacrylate or the like) and a corrosion inhibitor (a sulfur compound, a nitrogen compound or the like).
  • an extreme pressure agent an olefin sulfide, sulfurized fats and oils or the like
  • an abrasion-resistant agent a phosphate, a phosphite or the like
  • the lubricant composition When a lubricant composition of the present invention is applied to LSD of a car, the lubricant composition is excellent in frictional properties as the fresh oil and oxidation stability, chattering can be inhibited, change of frictional properties with the lapse of time is small, and abrasion on a metallic friction plate can also be minimized.
  • the lubricant composition of the present invention can be considered to be very valuable as the lubricant for LSD of cars.
